Two carts, one catalog
We designed a dual-cart system – Rentals Quote and Used Sales – that lives on the same product pages, so a production designer can build a rental list and shop used gear without ever losing context.
Case brief
Main Light is a professional stage lighting house with three facilities – Tri-State (NJ), East (DE) and West (NV) – running rentals, new sales and used sales off the same operation. We rebuilt the site on Next.js with two parallel flows so rental quotes and used-gear checkout could coexist without one smothering the other.

Brief and constraints
Client Brief
“We’re a trusted partner to lighting designers and rental houses, but the old site doesn’t say that. We need a platform that treats rentals, new sales and used sales as three different buying flows, shows what’s actually available at each location, and makes getting a quote as fast as a phone call.”
Challenges
Delivery path
We designed a dual-cart system – Rentals Quote and Used Sales – that lives on the same product pages, so a production designer can build a rental list and shop used gear without ever losing context.
Tri-State, East and West each have their own rental inventory pages. The UI makes location a first-class filter so users see what’s actually available where they’re shooting.
The quote flow mirrors how rental houses actually talk to crew – gear list, dates, contact – with persistent “Get a Quote” and 24/7 phone support in the header.
Result proof
Scope / stack / outcome
A persistent quote cart that lets crew build a multi-day, multi-unit rental list and send it as a structured inquiry – not a form dump.
A sales-ready e-commerce flow for used gear, living on the same site as rentals but with its own cart, shipping and checkout logic.
Per-location pages for Tri-State, East and West with local inventory, contact and news, so the brand can scale with each facility.
